A change in the region labeled y from U C G to U G C would most likely cause

Missing options:

A) the formation of recombinant DNA

B) the synthesis of a different polypeptide

C) crossing-over

D) polyploidy

B) the synthesis of a different polypeptide

Explanation:

The statement highlights a change in the codon sequence from UCG to UGC. If we look at the table of amino acids, we would realize that UCG encodes for "Serine" whereas UGC encodes for "Cysteine" amino acids. This single change in DNA sequence is known is mutation or single nucleotide polymorphism (SNP). Finally, the change in amino acid will result in the synthesis of a different polypeptide which contians a different amino acids. See figure attached for codon table.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

i believe the answer would be b. hope it : )
